Manley 12-14 Chrysler Hemi 6.4L 2.180in Head Dia Race Master Intake Race Flo Valves (Set of 8)

Starting with a 2.180-inch head diameter, these Manley Race Master intake valves are built for serious performance in Chrysler Hemi 6.4L engines. They are specifically crafted for racing applications, whether you're competing in bracket, drag, or oval track events, and are designed to handle engines running up to 8000 RPM. The goal here is to move as much air as possible into the combustion chamber, and these valves are a key part of that equation.

Manley uses a high-quality stainless steel for both the intake and exhaust valves, ensuring they stand up to the heat and stress of racing. The stems are chrome-plated and feature hard tips, which adds a layer of wear resistance for improved longevity. You'll also notice the swirl-polished under-head areas and fully machined combustion faces. This attention to detail helps optimize airflow around the valve head and improve combustion efficiency, making sure every bit of fuel and air is used effectively.

These particular valves are the Race Master style, which means they have a straight stem. Manley also offers a Race Flo shape, so you can choose what best suits your specific engine build. If you're building a high-performance Hemi and need components that can handle the demands of racing, these valves are a solid choice. They are also recommended for use in alcohol-fueled engines, particularly for the exhaust side, due to their robust construction.
